README

A simple module for a ZF2 app that will receive event webhooks from SendGrid and trigger a ZF2 event for each of the batched events received. You can then write your own listeners to do whatever you need to do with bounce processing etc.

Install

Install with composer using "netglue/sendgrid-webhook", enable the module in your application.config.php using the module name 'NetglueSendgrid' and add custom configuration to change the route url perhaps or set up Basic HTTP Auth (Recommended).

Test

cd to wherever the module is installed, issue a composer install followed by a phpunit.

Setup Basic Auth

Create a configuration file in your autoload directory named something like sendgrid.local.php and enter values for username and password as outlined in ./config/module.config.php.

Set an Alternate Webhook Endpoint/URL

Somewhere in your configuration files where you like to look after your routes, add a new one with configuration similar to this:

'router' => [
    'routes' => [
        'sendgrid-webhook' => [
            'options' => [
                'route' => '/somewhere/this-is-your-endpoint',
            ]
        ]
    ]
]

Setup SendGrid

Navigate to your account at SendGrid and access the Settings -> Mail Settings section. Click the Event Notification item and enter the url. By default, the URL should be something like: https://yourdomain.com/netglue-sendgrid-events.

Effectively, nothing will happen, but you should start to see something in your web server logs. You'll need to write some listeners to do something with the events triggered.

Write A Listener

For example, in your main app's Module.php you could setup a listener to log the events with something like this:

public function onBoostrap(EventInterface $e)
{
    // Get a logger instance - change this…
    $services = $e->getApplication()->getServiceManager();
    $logger = $services->get('TheNameOfMyLogger');
    
    // Listen to all events sent by the EventEmitter
    $em = $e->getApplication()->getEventManager();
    $sharedEm = $em->getSharedManager();
    $sharedEm->attach(
        'NetglueSendgrid\Service\EventEmitter',
        '*',
        function($event) use ($logger) {
            $params = $event->getParams();
            $logger->debug(sprintf(
                'Send Grid Event "%s" was triggered with the event name %s',
                $params['data']['event'],
                $event->getName()
            ));
        }
    );
}
